posix: Changed order of chown and chmod
Problem:
Rebalance process runs in the root mode. If a normal
user create a file and if it requires migration then
because the migrated file is created by root, its owner and
mode should be changed to the source normal user and
permission should be changed the previous mode. If
the suid bit is also set, then at the destination
suid bit should also be set.
Two operations are performed in the given order:
1. chmod
2. chown
But chown resets the suid bit. So changed the order
of these two operations so that first chown will be
performed and then chmod will be performd so that
suid bit will be preserved.
